This curriculum spans the technical and operational complexity of a multi-workshop integration program, addressing the same real-time data, event consistency, and system resilience challenges encountered in large-scale, distributed business environments.
Module 1: Architecting Real-Time Data Pipelines
- Selecting between message brokers (Kafka, RabbitMQ, AWS SQS) based on throughput requirements and delivery semantics.
- Designing idempotent consumers to handle duplicate messages in at-least-once delivery systems.
- Implementing schema evolution strategies using Avro or Protobuf to maintain backward compatibility.
- Configuring partitioning strategies in Kafka to balance load and ensure message ordering per business key.
- Setting up dead-letter queues to isolate and analyze failed message processing attempts.
- Choosing between push and pull models for downstream system integration based on latency SLAs.
Module 2: Event-Driven Integration Patterns
- Implementing event sourcing for order management systems to maintain a complete audit trail.
- Deciding when to use Command Query Responsibility Segregation (CQRS) to separate write and read models.
- Modeling business events with domain-specific payloads to avoid information leakage across bounded contexts.
- Enforcing event versioning and deprecation policies to manage consumer upgrades.
- Applying correlation and causation IDs to trace events across distributed transactions.
- Designing compensating actions for sagas in long-running business processes without two-phase commit.
Module 3: System Interoperability and API Design
- Exposing real-time capabilities via WebSockets or Server-Sent Events while managing connection lifecycle.
- Defining API contracts with OpenAPI and AsyncAPI to align frontend and backend expectations.
- Implementing circuit breakers and bulkheads to prevent cascading failures during downstream outages.
- Choosing between REST, gRPC, and GraphQL for synchronous communication based on payload size and client needs.
- Managing API versioning in production without breaking existing integrations.
- Securing real-time endpoints with OAuth2 and JWT token validation at the gateway level.
Module 4: Data Consistency and Transaction Management
- Implementing distributed locking using Redis or etcd for cross-service resource coordination.
- Using transaction outbox pattern to publish events atomically with database writes.
- Resolving data conflicts in multi-region deployments using conflict-free replicated data types (CRDTs).
- Monitoring and alerting on data drift between source and target systems in near real time.
- Designing retry mechanisms with exponential backoff and jitter for transient failures.
- Validating referential integrity across microservices without shared databases.
Module 5: Observability and Monitoring
- Instrumenting services with structured logging to enable automated parsing and alerting.
- Configuring distributed tracing to identify latency bottlenecks in event chains.
- Setting up real-time dashboards for message queue depth and end-to-end processing latency.
- Defining meaningful service level objectives (SLOs) for availability and freshness of data.
- Correlating logs, metrics, and traces using a shared context ID across services.
- Alerting on anomalous event rates using statistical baselining instead of static thresholds.
Module 6: Scalability and Fault Tolerance
- Designing stateless consumers to enable horizontal scaling in response to message backlog.
- Implementing graceful degradation by disabling non-critical event processing during overload.
- Configuring auto-scaling groups based on queue length or CPU utilization metrics.
- Testing failover procedures for message brokers in multi-AZ or multi-region deployments.
- Sharding event streams by tenant or region to isolate performance impact.
- Managing consumer group rebalancing in Kafka to minimize processing interruptions.
Module 7: Governance and Compliance
- Enforcing data retention policies for event streams to comply with GDPR or CCPA.
- Masking sensitive data in logs and traces before transmission to monitoring systems.
- Conducting audit trails by replaying event streams to reconstruct historical state.
- Classifying event data by sensitivity level to control access and storage encryption.
- Documenting data lineage across systems to satisfy regulatory reporting requirements.
- Implementing change control for event schema modifications using automated approval workflows.
Module 8: Deployment and Lifecycle Management
- Rolling out new event consumers using blue-green deployment to minimize downtime.
- Validating backward compatibility of event schemas before deploying producer updates.
- Scheduling consumer deployments during low-traffic windows to reduce risk.
- Automating rollback procedures when event processing error rates exceed thresholds.
- Managing consumer offset migration during platform upgrades or broker reconfiguration.
- Using feature flags to enable or disable real-time processing paths during incidents.
